IMPROVED HOSE OR TUBING.

Specification forming part of Letters Patent No. 39.237, dated J uly'14,1863.

ofMas'sachusetts, haveinvented certain new a id useful Improvements inthe Manufacture of Hose orTubing for Conveying Liquids; and

I do hereby declare. that the following description, taken in connectionwith theaccompanying drawings, hereinafter referred to, forms a full andexact specification of the same, wherein 1 have set forth the nature andprinciplesof my said improvements, whereby my invention may bedistinguished from all others of asimilar class, together with suchparts as I claim and desire to have secured to me by Letters Patent.

In originating the present invention, the principal object has been tocombine the flexibility of hose or tubes composed of woven or braidedfibrous materials with the imperviousnoss to water or moisture of rubberor guttapercha.

' It has been demonstrated in practice that, while there are greatadvantages attending the use of hose, for conveying liquids underpressure, made from fibrous materials, there is a great disadvantageproceeding from the fact that the strandsor threads absorb and retainfora long time the water or moisture with which they may come incontact, the eflect being to mildew and rot this kind of hose in a shorttime.

.with a tube or hose of the required bore. By 'this means, whileretaining all the flexibility and lightness of hose composed of wovenfibrous materials,.1 also obtain all the imperviousness to moisture andconsequent durability of india-rubber or gu'tta-percha, the tendency ofthe tube thus formed to mildew and rot being entirely prevented.

The figures of the accompanying plate of drawings represent my improi edhose or tubing. l

Figure 1 is-aplan or top view. Fig. 2 is a transverse section.

The precise form of hose may, it is obvious, be considerably modified,as the woven tube may, for example, have an inner lining of rubber orgutta-percha, and an outer tube of the same materials may (but I do notthink it betslt) be slipped over the water proof woven to e.

' The mode that I prefer to make my improved hose is to first takethreads or strands of the desired size and then saturate or cause to beincorporated with them rubber or gutta-percha (reduced to a properconsistency) by passing them through friction-rollers with the rubber orgutta-percha, in the manner well-known to rubber manufacturers. Thethreads'or strands thus prepared; may then be dried or cured byartificial heat or by the vnlcanizing process, and are then woven into aweb or tube on a loom. 1f woven in the form of a flat web, the lattermay be united at its two edges by riveting or otherwise, but I prefer toweave or braid them into a circular tube without a seam;

It will be evident that the threads orslrands, after being renderedwater-proof, as above described, may be woven or-braided either by handor by machinery, and either before or after they are cured...

Having thus described my improvements,.

what I claim as my invention, and desire to have secured to me byLetters Patent, is-'-- Forming a hose or tubing by first saturating orincorporating, with threads or strands of fibrous materials, rubber orgutta-percha, or compounds ot'eith er or both, and'then weaving orbraiding the same, substantially as set forth.
